Those elements, with electronic configuration of valence shell ns2np6 show little tendency to react chemically, are called:
Correct answer: D. Noble gases
- A. Lanthanides
- B. Actinides
- C. Alkali metal
- D. Noble gases
Explanation
Elements with the electronic configuration of valence shell ns²np⁶ are known as noble gases. These elements are chemically inert due to their completely filled valence electron shells, making them highly stable and unreactive with other elements.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
